The application is a divisional application of a leg ligament stretching training device for dance teaching, wherein the application date is 2018, 06, 28 and the application number is CN 201810686520.0.
Technical Field
The invention relates to the technical field of sports goods, in particular to a leg ligament stretching training device and a training method for dance teaching.
Background
Dance is a kind of performance art, uses the health to accomplish various graceful or highly difficult movements, is fit for the crowd of each age bracket, and many children practise dance by oneself.
There is one to press the leg training in the exercise process of dance, its mainly for the ligament of shank is stretched the flexibility that increases the shank, dance training is when carrying out the tensile shank ligament of press leg at present, generally all can need the outsider to carry out the supplementary promotion that pushes away and forces the nature tensile process, painful sense is stronger, and cause the shank ligament injury extremely easily, the extrusion force degree can not be in time the root type training person's dynamics of bearing adjusts, in addition, just carry out the tensile ligament training of press leg through modes such as horizontal pole, this kind of mode generally all is the one-leg and operates, efficiency is lower relatively, and the full name is in the state of standing, great to physical demands.
If Chinese patent discloses a ligament stretcher (patent number: CN104622664B), which comprises a foot rest, a track frame, a base, a roller, a backrest, a hand-operated wheel, a leg placing plate, a sliding strip, a shank fixing belt, a cable, a pulley A, a pulley B, a hip fixing belt and a hand-operated lifter, although the device can play a role in stretching and training ligaments, the device still has some defects: its occupation space is great relatively, is not suitable for dance classroom teaching training usefulness, and dance teaching shank stretches the training that only goes on in certain time quantum in addition, and individual purchases alone and carries out the too big unsuitable large tracts of land of training cost and promote.
